1 Claim. (01. 160-107) This invention relates to, a new and improvedwindow blind and rain proof ventilator' which has as its primary objectthe provision of an arrangement comprising a screen and metallic slatspositioned within a window frame, outside of a window, to regulate thelight entering ayvindow and which will form, when desired, a rainproofshutter which allows free ventilation through the window.

Another object of this invention isf the provision of a device of thecharacter described which is quickly and easily operable into severalpositions and which is easily applied to a conventional window.structure. 7 j

Still-@nother object of this invention is the provision of a device ofthe character described which'is of durable yet simple and -inexpensivedesign and a device which has the'viminimum of working; parts whichmight, with use, become worn and broken.

Still-further advantages and improvements of this invention will readilyappear to -those skilled in the, art when the following descriptionisread in the'j light of the accompanyingdrawings in which:

Fig. 1 is a front elevation of the blind.

Fig. 2 is a vertical section taken on line 2-2.

Fig. 3 is a horizontal section taken on line 33.

Fig. 4-is a vertical section taken' on line 4-4.

Fig. .-is a vertical section taken o n line 5-5.

Fig. 63 is a vertical section takenon line 6-6.

Referring now to the drawings ;in which like numerals indicate similarparts} throughout A designates a window frame housing the conventionalsashes I and 2 of the window.

A second frame 3 adapted to be securely fitted the frame A from the ouQde of the winshaft- ,8 mounted in said bea r gs is a slatted.

blind *9 comprising a plurality, .thorizontal slats l0 rotatably mountedon shafts ll identical to the shaft 8 which corresponds to the shaft llof thefupper most slat. The outside longitudinal edgetqf each of theseslats was curved upward as atflZ and secured as at 13 to two tapes lland I5 which interconnect the upper most and lower most slats on theiroutside edges, while two similar tapes l6 and I1 interconnect the uppermost and lower most slats on the inside but these tapes are not securedto the intermediate slats as are tapes [4 and I5.

A blind cord B is secured as at I8 to one end of the shaft ll of thelower most slat and then passed upward over the upper pulley wheel 5 andthen looped downward under the pulley wheel 5 at the lowerocorner, thenhorizontally around the wheel 6 and back around the lower wheel 5 andupward to the shaft II where the opposite end of the cord is securedadjacent the first end at l9.

This cord arrangement is effected on both sides of the frame, so that aturning of the wheel 6 will cause the end ill to be pulled upward overthe upper pulley wheel simultaneously allowing the needed amount ofslack to accumulate at 19 to allow the opposite end to play upward withthe first end.

This arrangement allows the blind to be raised or lowered.

The tilting of the blind is accomplished by a hand lever 20 which isrotatably secured at its upper end, as at 2|, to a crank arm 22 which isafiixed to the end of shaft 8, or II, of the upper most slat.

By moving said lever arm upward crank 22 rotates shaft 8, or II, so thatthe outside edge 23 ,of the slats I0 is tilted downward to approach theupper curved end l2 of the slat I 0 below it.

This provides that the slats may be moved to form a solid enclosure asshown in Fig. 6 or they may be positioned in any intermediate closingstate.

The lower end 24 ofthe lever arm 20 is adapted by a, hooked end 25 toengage one of a plurality of detents 26 spaced vertically in a plate 21secured to the bottom corner of the frame 3.

This arrangement provides for the securing of the slats in theirdesiredrtilted position.

I Having thus described the structure and operation of this invention,what I claim is:

A combination screen and slatted blind for wining therewith; tapesconnecting said slats; a plurality of intermediate slats spaced over thedistance between said first-named slats and connected to the tapes; 2.pair of upper and a pair of lower pulleys rotatably mounted at the upperand lower corners of the screen frame respectively; an operating pulleyrotatably mounted at the lower end of the screen frame and disposedmidway between the" lower corner pulleys; and a pair of blind cords,each cord being-secured at one end to one end of the lower shaft andbein trained ardly from said lower shaft along a, side of the screenframe over one of the upper.

corner pulleys and extending downwardly from said upper corner pulleyaround one of the lower corner pulleys and being wound upon theo'purafit ing pulley.
